The iris diaphragm is manually adjusted until the exposure field indicator needle is visible in the view- finder, to the left, in the middle measurement field. The middle measurement field stands for correct exposure in a „normally bright“ scene, the outer points + and - show over- and underexposure of approximately two aperture stops.

ARRIGLOW

The illuminated frame viewfinder with variable brightness control - ARRIGLOW - facilitates filming in which due to the prevailing lighting conditions it would otherwise be difficult or impossible to see the format mark- ings. It can be minutely adjusted to suit every lighting situation.

•Set the desired brightness with the adjustment wheel

.

If using effects filters such as strips of gauze on the back of the lens, or if the back of the lens is dirty, the entire viewfinder will be brighter.

ARRIGLOW and the exposure meter can only be used as alternatives to each other. Therefore it is recommended when using ARRIGLOW to proceed in the following manner:

•Switch to exposure meter.

•Set the aperture stop.

•Switch to ARRIGLOW.
